Hari ini adalah Patch Tuesday Desember 2021 Microsoft, dan dengan itu datang perbaikan untuk enam kerentanan zero-day dan total 67 kerentanan keamanan. Pembaruan ini mencakup perbaikan untuk kerentanan Installer Windows yang dieksploitasi secara aktif yang digunakan dalam kampanye distribusi malware.

Microsoft telah memperbaiki 55 kerentanan (tidak termasuk Microsoft Edge) dengan pembaruan hari ini, dengan tujuh diklasifikasikan sebagai Kritis dan 60 sebagai Penting.

Patch Tuesday kali ini juga mencakup perbaikan untuk enam kerentanan zero-day, dengan satu kerentanan Installer Windows AppX yang dieksploitasi secara aktif.

Kerentanan zero-day Installer Windows AppX yang dieksploitasi secara aktif dilacak sebagai CVE-2021-43890 dan digunakan dalam berbagai kampanye distribusi malware, termasuk Emotet, TrickBot, dan BazarLoader.

Kerentanan tersebut dapat dieksploitasi dari jarak jauh oleh aktor ancaman dengan hak pengguna rendah dalam serangan kompleksitas tinggi yang membutuhkan interaksi pengguna.

Untuk memblokir upaya eksploitasi, pengguna Windows harus menginstal Installer Desktop Microsoft yang ditambal untuk platform mereka:

  • Microsoft Desktop Installer 1.16 for Windows 10, version 1809 and later
  • Microsoft Desktop Installer 1.11 for Windows 10, version 1709 or Windows 10, version 1803

Microsoft juga menyediakan langkah-langkah mitigasi bagi pelanggan yang tidak dapat segera menginstal pembaruan Microsoft Desktop Installer.

Mitigasi yang direkomendasikan termasuk mengaktifkan BlockNonAdminUserInstall untuk mencegah non-admin menginstal paket Aplikasi Windows dan AllowAllTrustedAppToInstall untuk memblokir pemasangan aplikasi dari luar Microsoft Store.
